Admiral Whisker's Mother - Doom Patrol (2019)

A common woodland rat that ended up near the manor house of Niles Caulder, the unnamed mother - of the rodent that would eventually become known as Admiral Whiskers - was attempting to teach her child about country road traffic awareness and safety when she was run over by a speeding bus.

Her death impacted heavily on her son, who, with the goading of Mr Nobody took on a new identity and set about seeking vengeance of Cliff Steele, the one who had been driving at the time.
